The branch, master has been updated via 6678907 s3:vfs_gpfs: Use directory not file to get fileset id from f31d0d0 vfs_media_harmony: fix some compile warnings with llvm
http://gitweb.samba.org/?p=samba.git;a=shortlog;h=master - Log ----------------------------------------------------------------- commit 6678907fae43e0d25b578b4e649a2fbd9c5e9d71 Author: Christof Schmitt <christof.schm...@us.ibm.com> Date: Thu Aug 16 12:47:52 2012 -0700 s3:vfs_gpfs: Use directory not file to get fileset id The query of the fileset quota needs to determine the file set id first. With the currently available interface, this requires opening the file to get a file descriptor. For files, this open can fail when a share mode is set. Workaround this by querying the fileset id on the directory instead. The proper solution would be getting an interface for getting the fileset id that does not require opening the file.
